Pitfalls	Tips
1. It is difficult to make a posterior root footprint in the anatomic position and secure the graft through a tight posteromedial joint space. 2. Sometimes, the posterior root of the allograft is bent and loosened after fixation.	1. The posterior bone plug is reduced for the bone shell containing cancellous bone. 2. Superficial medial collateral ligament release is performed using a periosteum elevator to obtain increased medial compartment opening. 3. Leading suture of bone plug is pulled out via the anterolateral side of tibia to provide firm fixation.
